Chafe-iron.



`hUNITED STATES WILLIAM H. LOPER, OF BELLGROVE, IDAHO, ASSIGNOR OF ONE-HALF TO- PATENT A. A. CRANE, OF HARRISON, IDAHO.

CHAFE-IFKON.

T0 all whom, it may concern:

Be it known that I, WILLIAM H. LOPER, a citizen of the United States, residing at Bellgrove, in the county of Kootenai and State of Idaho, have invented new and useful Improvements in Chafe-Irons, of which the following is a speciiication.

My invention pertains to chafe-irons for use on wagons and other vehicles; and it consists in the peculiar and advantageous construction hereinafter described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of so much of the runninggear of a wagon as is necessary to illustrate the application of my novel chafe-iron. Fig. 2 is an enlarged detail section taken in the plane indicated by the line 2 2 of Fig. 1 and illustrating the reach or coupling-pole of the running-gear and the antifriction-rollers of my chafe-iron in side elevation. Fig. 3 is a detail transverse section taken in the plane indicated by the line 3 8 of Fig. 2, and Fig. 4f is a detail plan view illustrating the manner in which the antifriction-rollers of a chafe-iron are secured in the body thereof.

Similar letters designate corresponding parts in all of the views of the drawings, re-

ferring to which- A A are the hounds of a runninggear,which are provided with an upper slider B and a lower slider C, the latter being located in a vertical plane in rear of that of the slider B,

as clearly shown in Figs. 1 and 2.

D is the reach or coupling-pole of the running-gear, which extends between the two sliders, and E is the chafe-iron constituting the present and preferred embodiment of myv invention. The said chafe-iron comprises a sleeve-like body a, which is made of cast metal and is ofa size to snugly receive the reach or coupling-pole D, an antifriction-r'ollerb, journaled in the body a and arranged to engage the under side of the upper slider B, and a lower antifriction-roller c, journaled in .the body and arranged to travel over the upper side of the lower slider C, all as best shown in Fig. 2. The antifriction-rollers b and c are secured in the body a after the manner best shown in Figs. 2 to LL that is to say, a trunnion Z at one end of each roller is let into a socket e at one end of an oblong opening f in the body a and a trunnion g at the opposite end of the roller is retained in position by Specification of Letters Patent.

a plate h, connected to the body a through the medium of' a bolt ri. There are two of the ybolts 7,' employed, and with their complemen-l tary nuts j' they serve, in addition to connecting the plates /L to the body a, to connect and fix the said body to the reach or coupling-pole D, as shown.

. To permit of the bearings of the upper roller being lubricated with facility, I provide a lubricant-duct 7c in the upper side of the body a and a lubricant-duct Z in the upper plate z, while for the same purpose with reference to the lower roller c I provide lubricant-ducts m, Figs. 2and 3, which extend inwardly and downwardly from one side of the body a; to the bearings of the said lower roller.

In practice my novel chafe-iron is arranged on and connected to the reach or couplingpole D and is disposed as shown relative to the upper and lower sliders B and C of the hounds A. In virtue of this arrangement of the chafe-iron and the fact that the antifriction-rollers and c are longer than the width of the sliders B and C it will be observed that incident to the movements of the sliders with culated to materially prolong the usefulness of a running-gear, which is an important de-v sideratum.

The arrangement of the slider B in' advance of the slider C and the arrangement of the antifriction-roller Z2 in advance of the roller c are advantageous for the reason that such arrangements conduce materially to the strength and durability of the structure as a whole.

Notwithstanding the advantages which I have ascribed to my novel chafe-iron in the foregoing description, it will be noted that the chafe-iron is simple and inexpensive in construction and is susceptible of ready application to the reach or coupling-pole of a wagon at present in use, as Well as to the reach or coupling-pole of a new wagon.

.While I have stated that the body a of the chafe-iron is formed of cast metal, I desire it understood that the said body and all of the other parts of the iron may be formed of any suitable material or materials without involving departure from the scope of my invention. f

I have entered into a detailed description I plane in front of the other, a reach or coup'- of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as coniining myself to such specific construction and relative arrangement of parts`v as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim, and desire to secure by Letters Paten t,

In a running-gear, the combination of hounds having upper and lower sliders; one of the said sliders being arranged in a vertical ling-pole extending between the said sliders, and a chafe-iron comprising a sleeve-like body surrounding and receiving the reach or coupling-pole and iixedly connected thereto, and upper and lower antifrictio|irolleis mounted lengthwise in the said sleeve-like body and arranged one in front of the other and in engagement with the said sliders of the hounds.

In testimony whereof- I have hereunto set my hand in presence of ltwo subscribing witnesses.

WILLIAM H. LOPER.
